| Abstract: | The authors study geometry aspects of damage in concrete structures by fractal geometry theory. The application conditions of fractal dimension analysis are discussed. The appearance damage, crack ratio, total extension and diverge elongation of cracking are quantified. The relationships between fractal characteristic values, strength and width of crack are investigated. This study introduces a new quantitative analysis means for evaluating geometry aspects of damage and durability of concrete structures. |
